Santa Rosa Island ManzanitaArctostaphylos confertiflora

Santa Rosa Island manzanita thrives with infrequent watering once established, especially in its native Mediterranean climate.

Water deeply during prolonged dry spells in summer to prevent stress, but ensure excellent drainage to avoid root rot. Allow the soil to dry out considerably between waterings.

Pruning is typically minimal, mainly for shaping or removing dead, damaged, or crossing branches. Perform any necessary pruning after flowering has finished in late spring or early summer.

Avoid heavy pruning, as manzanitas are sensitive to significant cuts into old wood.

Propagation is best achieved through cuttings taken from semi-hardwood in late summer or early fall. Rooting can be slow and may require bottom heat and high humidity.

Germination of seeds is difficult and erratic, often requiring stratification.

Repotting is rarely necessary for Arctostaphylos confertiflora, as it prefers to remain undisturbed and has a sensitive root system.

If a container specimen becomes root-bound, repot in spring to a slightly larger container with well-draining, gritty soil. Handle roots gently.
